MECHANISM FOR ATTACHING WINDOW FIXTURES.

Application filed February 24, 1927. Serial No. 170,523.

The present invention relates to an arrangement for attaching fixtures to sheet metal windows where either because of cost or because the metal of the window is of too light gauge, it not desirable to tap the holes formed in the sheet metal, and where lack of accessibility does not permit the fixture to be bolted on.

For the purposes of illustration, I show my invention as used for attaching a roller shade bracket, but it is to be understood that various other fixtures such as curtain rod supports, tie-back hooks etc. may be connected in the same way. as the device can be made very strong so that it will carry heavy loads.

In the accompanying drawing, Fig. 1 is a fragmentary section through the inner wall of a jamb with the fixture in place; Fig. 2 is a front view of the parts shown in Fig. 1, and Fig. 3 illustrates a modified arrangement.

The numeral 2 designates the sheet metal of which the window jamb is formed, in which are two holes 4 and 6. The fixture has a back plate 8 to which is connected (preferably the two are made integral) a bar 10 which is bent around so that if the portion near the plate 8 is in the hole 4, the other end will. extend through hole 6. Intermediate the two ends. the bar 10 is given a reverse bend as at 12 and the free end is threaded to take a nut 14. The desired fixture is formed in. made integral with. or attached to the back plate 8. In the present example this plate is slotted as shown at 16 and the line of the slot is carried forward by the web 18 to receive the flat end of an ordinary spring shade roller.

The holes 4 and 6 are formed in the metal of the jamb and the-threaded end of bar 10 is inserted through one of the holes. 3 pressing on the upper end of plate 8, the lhreaded end of rod ll) will be pressed againstthe rear side of the sheet metal jamb, so that if the bar moved. around to the proper position, this end will come forward through the other hole. The nut 14 is then screwed on until the roc, fulcruming about reverse bend l2, draws plate 8 tight against the j amb face 2.

The fulcrum point 12 is here shown as about midway between the ends of rod 10; and the nut 14 is shown below plate 8. If desired, the fulcrum point may be moved nearer plate 8 and thus the leverage of nut 16 may be increased. Also the device may be inserted other end up, which will be desirable if the fixture is to extend any distance out from the face of the jamb and carry a load near its to as the strain will then tend to hold the ulcrum point against the rear face of the jamb and take any strain off the nut. This is illustrated in Fig. 3 where a curtain rod support 20 is connected with a back plate 8.

lVhat I claim is:

1. A mechanism for use in combination with a sheet metal structure having two spaced holes, comprising a fixture, a back plate connected therewith, a rod connected with the back plate adapted to pass in one hole and out the other, a nut for the free end of the rod, and a fulcrum point formed on the rod adapted to contact with the sheet metal structure so that when the nut is screwed up, the back plate will be drawn against the sheet metal structure.

2. A combination as specified in claim 1, in which the nut is above the back plate so that a load on the outer end of the fixture will tend to force the fulcrum point against the sheet metal structure, and relieve the nut of strain.

3. An attaching mechanism for metal structures or the like having two holes there through, comprising a bolt adapted to be passed in through one of said holes, means for holding one end of such bolt on the side of such structure from which the bolt is passed in, a fulcrum point on the bolt adapted to lie within such structure between said holes when the bolt is in place and threaded means adapted to pass through said second hole whereby said fulcrum. point may be drawn up tightly against the inside of the wall of such structure.

4. A structure as defined in claim 3, in Ivyliich the threaded means is a portion of the AMSON G. ILLOH.
